Description

Optical Isolator, Passive Isolation Of Linearly Polarized Light, PBS+Quarter Waveplate

Overview:

Optical isolator is a combination of a Polarizing Beamsplitter Cube (PBS) and a Quartz Quarter Waveplate. Incident light is linearly polarized by PBS and converted to circular polarization by the quarter waveplate when light first travels through it. Any portion of the emerging beam reflected back into the isolator and goes through a second time of the quarter waveplate will be converted into a linearly polarized beam which is perpendicular to the input beam. This beam is then blocked by PBS and it will not return to the original input path of the system.
